Double Dragon

Relatively simple if you use the + combination and moving around the screen. When you reach the final boss it is best to focus on him only. Stay close to him and use the elbow. If you get hit by the other enemies don’t worry about them, just focus on the boss. It is best to have most if not all of your lives in hand when you get to this part just to be safe because one shot from the boss’s gun will kill you.
